A kid is on the train. Ok, sounds normal, but this time it’s 2 kids, a brother-sister pair! Well anyway, the siblings’ mother died of illness when they were really young. Their father remarried, and the kids got along as well as possible with their stepmother, until one heated argument about the stepmom missing an important event (birthday, christmas, etc) ends with the kids going to their rooms in anger after wishing they didn’t have a stepmom anymore, and right as they go to apologise, dad tells them that stepmom died in an accident, and this time he’s never gonna remarry again. After an argument with dad, the kids run away, and they end up on the Train. What do you think?
